"I've always been a writer. My songs are the door to every dream I've ever had and every success I've ever achieved," says Dolly Parton of her incredible career, which has spanned nearly five decades and is showing no signs of slowing down. An internationally renowned superstar, the iconic and irrepressible Parton has contributed countless treasures to the world of music entertainment, penning classic songs such as "Jolene," "Coat of Many Colors," and her mega-hit "I Will Always Love You." With 1977's crossover hit "Here You Come Again," she successfully erased the line between country and pop music without noticeably altering either her music or her image. "I'm not leaving country," she said at the time, "I'm just taking it with me."
